Epileptiform Activity in Neurocritical Care Patients

The Canadian Journal of Neurological Sciences, 05/11/2012

Approximately 7–8 neurocritical care patients must undergo intermittent EEG monitoring in order to diagnose one with periodic epileptiform discharges (PEDs) or seizures. The predictors the authors identified could potentially help guide use of resources. Repeated intermittent studies, or continuous electroencephalography (cEEG), should be considered in patients with multiple risk factors, or when interictal discharges are identified on an initial EEG. It remains unclear whether aggressive prevention and treatment of electrographic seizures improves neurologic outcomes.
